CHP Officer Ming Hsu said Kardashian was pulled over at about 1 p.m. on the 101 Freeway near the Van Nuys Boulevard exit. Three other cars apparently driven by paparazzi were also stopped, although two of them left the scene before an officer was able to talk to the photographers, according to a news release.

The third photographer, Juliano A. Goncalves, pulled around Kardashian's vehicle and started taking pictures. He was cited for speeding and stopping in a nonemergency situation, Hsu said.

Kardashian, 33, who stars along with her family in the reality series "Keeping Up With the Kardashians," has generally had a good relationship with the paparazzi. Her fiance, rapper Kanye West, however, has had several skirmishes with celebrity photographers.

STUDENTS PROTEST AGAINST NAPOLITANO AT UC MEETING: SAN DIEGO (AP) — A group of protesters say they want former Homeland Security Secretary Janet Napolitano to step down from her new job as president of the University of California.

Napolitano attended her first Board of Regents' meeting Tuesday but was not present during the public comment session when some of the protesters spoke at the meeting at the University of California San Francisco. Napolitano took her seat later.

Many of the protesters were high school students who said Napolitano is the wrong choice and will instill fear in immigrant students because she oversaw a large number of deportations in her previous position.

Napolitano in the past has defended her track record on immigration, saying she has been an advocate for the federal DREAM Act and immigration reform.

20 TOP SCIENTISTS URGE GOVERNOR TO STOP FRACKING: SACRAMENTO (AP) — Twenty of the nation's top scientists have sent a letter to California's governor urging him to place a moratorium on the controversial practice of hydraulic fracturing, or "fracking."

They say the practice increases pollution and runs counter to Gov. Jerry Brown's efforts to cut the state's emissions.

In the letter, the group argues that Brown can't say he wants to reduce global warming while also expanding fossil fuel development in California.

Brown has come under increasing criticism from opponents of fracking, which injects water, sand and chemicals into the ground to fracture underground rock formations and release fossil fuels.

The letter's signatories include Anne Ehrlich and Paul Ehrlich of Stanford University, Alastair Iles of the University of California, Berkeley, and Shaye Wolf of the Center for Biological Diversity.

MAN HELD FOR DIDGERIDOO ATTACK ON CAB DRIVER: CHULA VISTA (AP) — A Southern California man has been arrested after police say he whacked a taxi with a didgeridoo in an argument over the fare.

The 31-year-old man and a woman were picked up Sunday night in Chula Vista then fell asleep during a 20-minute ride to a home.

Police Lt. Phil Collum says when they arrived, the man got into an argument with the cabbie over the fare.

Collum says he went into the house and came out with a didgeridoo — a long, wooden instrument from Australia.

Collum says the man threatened the driver with it. The cabbie drove off, but the man allegedly chased the cab and whacked it several times with the didgeridoo, denting the vehicle.
